Auditory EEG and Behavioral Assessments in Individuals With Rett Syndrome
調査の概要
詳細な説明
This study is an observational research project conducted under a broader IRB approved protocol that includes multiple neurodevelopmental and neurodegenerative conditions. The current ClinicalTrials.gov record describes only the Rett syndrome component of the research and reflects the procedures currently being performed for participants with Rett syndrome and age/sex-matched controls.
All participants in this study will undergo a noninvasive electroencephalogram (EEG) recording to measure brain responses to auditory stimuli. During the EEG, participants will listen to simple sounds through headphones while brain activity is recorded. No behavioral responses are required during the EEG recording.
Parents or caregivers of participants with Rett syndrome will complete questionnaires related to the participant's medical history, Rett syndrome symptoms, communication abilities, daily functioning and overall health. A structured interview may also be conducted with the parent/caregiver to assess adaptive behavior. In addition, a Rett syndrome severity scale may be completed by a clinician or trained member of the research team.
Control participants (or their parent/caregiver) will be asked to complete a demographics questionnaire.
This study does not involve assignment to a treatment or intervention, and does not involve the use of FDA regulated drugs or devices. Optional procedures described in the umbrella protocol such as Magnetic Resonance Imaging (MRI) studies are not part of the current Rett syndrome workflow and are not included in this study record.
The primary purpose of this research is to collect observational brain activity and clinical data to better characterize Rett syndrome and to support future scientific and clinical research.

Rett Syndrome Participants
Individuals with Rett syndrome who participate in this observational study will undergo a noninvasive electroencephalogram (EEG) recording while listening to simple sounds through headphones.
Parents or caregivers will complete questionnaires and interviews related to the participant's symptoms, communication abilities, daily functioning and overall health.
A Rett syndrome severity scale may also be completed by a clinician or trained member of the research team.

Participants will undergo a noninvasive electroencephalogram (EEG) recording to measure brain activity in response to auditory stimuli.
During the procedure, participants will listen to simple sounds through headphones while brain signals are recorded.
No behavioral responses are required.

Age- and sex-matched controls
Individuals who are age- and sex-matched to Rett syndrome participants in this study will be enrolled as controls.
Control participants must have no medical history of genetic, neurological, or psychiatric disorders, no history of special education services, and no hearing impairment.
Control participants in this study will undergo a noninvasive electroencephalogram (EEG) recording while listening to simple sounds through headphones.
Control participants (or their parent) will also complete a demographics questionnaire.
